Abstract
A process for the manufacture of plated strips comprising at least two layers of different metals or alloys. The process allows subsequent separation of different cropped layers resulting from shearing the plated strips. The process comprises preparing plates corresponding to each of the plating layers, superimposing and assembly of these plates to form a composite plate, hot and possibly cold rolling of this composite plate to obtain a plated strip, and shearing of cropping areas during or after rolling. In one embodiment, prior to superimposing the different plates, an anti-sticking agent is applied to the cropping areas of at least one of the surfaces of the plates which will be in contact with each other.
